number 1 cylinder burning to rich

poss leaking injector causing wash down of cyl leading to lack of compession,are you sure its cyl#1 or bank #1?

Had this same problem. Cyclinder 1 is misfiring. My mech said to take off the plug wire, blow this area out and make sure it is dry. Also put dielectric grease on both ends of the plug wire. This will help keep out the moisture.
